Elastomeric Seals - Materials requirements for seals used in pipes and fittings carrying gas and hydrocarbon fluids
This European Standard specifies requirements for elastomeric materials used in seals for supply pipes and fittings, ancillaries and valves at operating temperatures in general from - 5 °C up to 50 °C and in special cases from - 15 °C up to 50 °C, for the following: General applications (see Table 4, type G) a) gaseous fuel (manufactured, natural and liquefied petroleum gas [LPG] in gaseous phase); b) hydrocarbon fluids with aromatic content up to 30 % (V/V), including LPG in liquid phase. Special applications (see Table 4, type H) Materials suitable for carrying gaseous fuels containing gas condensates and hydrocarbon fluids of unrestricted aromatic content. General requirements for finished joint seals are also given; any additional requirements called for by the particular application are specified in the relevant product standards taking into account that the performance of pipe joints is a function of the seal material properties, seal geometry and pipe joint design. This European Standard should be used where appropriate with product standards which specify performance
